Thesis abstractThe formation and decay of a chimney from the inactive Sonne hydrothermal site was investigated by microscopic and geochemical analyses. EPMA and LA-ICP-MS analyses reveal the partitioning of elements between sulfide phases and complement textural interpretations. Both, bulk chemistry and bulk mineralogy show the typical zonation of black smoker chimneys: In the Cu - zone fossil orifices are lined by chalcopyrite. The Fe - zone is dominant towards outer parts of the chimney, where dendritic and colloform pyrite become more abundant. The Zn - zone contains zinc sulfides; barite and amorphous silica fill former conduits.The paragenetic sequence of minerals reveals that the black smoker formed during four phases. Phase one represents the onset of chimney growth that started with the precipitation of dendritic and colloform pyrites. During phase two, the conditions stabilized and elongated chalcopyrite and euhedral pyrite formed. Phase three marks the waning of hydrothermal activity, when zinc sulfides precipitated under both, cooler temperatures and higher pH. In addition, covellite formed, when a high Cu bearing fluid was introduced. Amorphous silica coated all sulfides and prevented their disintegration and alteration. Pyrite is thought to have precipitated directly from the hydrothermal solution without formation of precursors. Additionally, the FeS content of zinc sulfides indicates that the hydrothermal fluid prevailed in the pyrite stability field at elevated fS2 values and temperatures below 300°C. Increased Se contents of pyrite are used as an indicator for a smaller influence by seawater. Zn, Pb, Ag and Au were remobilized during a later stage of hydrothermal activity. Especially, Au and Ag correlate with marcasite, which is found with layered pyrite at the exterior of the chimney. A search for these precipitations provides an initial approach for further sub-seafloor exploration.
